RADIUS-ROD FOR AUTOMOBILES.

Patented Apr. 3, 1%1. '3'.

Application filed April 17, 1913. Serial No. 761,859.

To all whom it may concern:

Be it known that I, BEoKaI'c CHRISTIAN KNUnsnN, a citizen of the United States, residing at Clinton, in the county of Clinton have. invented a new and useful Radius-Rod for Automobiles, of which the following is the specification.

. My invention relates to radius rods emand hold in position the front axle of an automobile of the type consisting of two rods meeting and joined to gether at an angle, at which point an enlargement of globular form is situated and contained in a ball and socket bearing at tached to the bottom of theengine and crank case. From this point the radius rods each V extend diagonally forward to the front axleat the point where the hanger carrying the end of the front spring is-situated. At this point the front end of said radius rod is fastened by being inserted into a hole in said spring hanger and is securely held in place by a nut.

My invention to said radius rods at a point between the two extremities and extending to that point on the lower side of said front axle where the end of the spring a threaded bolt protrudes through a hole in the axle, the end of said brace rod which is of a shape suitable for the purpose is attached to said lower end of said "spring hanger and by means of a nut securely fastened thereto.

\ Fig.

The object of my invention is to reinforce and strengthen said front radius rods so that they will resist the violent j ars' imparted to them on the road, and yet maintain their original shape, thereby successfully serving to keep the front axle in alinement and\ facilitate safety and the easy steering -.quali- 'ties of the automobile. All illustrated in the accompanying drawing of which- Figure 1 shows the front radius rods of an i of the front axle with my brace rods attached 2 represents my brace rods with the clamping device open showing the depressions forreceiving the radius rods near their junction. Also the cover 11 and bolt-'17- and nuts 16 which fasten it to the frame of the automobile.

Fig. 3 shows the nut with taper eat hold-j 'ing the front end of the lower radius the spring hanger.

Fig. 1 shows my brace rodsattachedto the e consists in a brace attached" hanger in the orm of. ,end, in

crank case. radius rods-with a ball radius rods and axle of an automobile. 1 represents the ball extremity of the radius rods as used on an automobile. the ball is a metallic rod or neck 2.which at once forms a folk 3 by dividing into two diverging radius rods 4 and 5 which at this Attached to junction point near the ball meet at an acute angle.

The distal extremity of rods 4 and-5" ex tend forward and laterally, until they reach :3?

the front axle 6 at the point where the bolt 7 of the spring hanger 8, 8 perforates a hole velop the fork 3 of the radius rods and is vmadein two halves held together by means of a bolt and nut 17 and at the same time clamping the fork 3 of saidradius rods.

From the lower half 12 of the clamps, extend two rods 13 and 14 forward to the front axle. Each one terminating in aflattened whichthere is a hole 15 penetrated by the lower end of bolt 7 as it emerges from the lower side -of the front axle.

The hole 15 isbeveled nearly the en tirijg'g thicknessof the material and a nut 16 with; a beveled seat, screws onto the end of bolt 7 holding the bolt 7 as well as the front end' of rod/'13 and 14 firmly in place.

The brace rods referred to can be made as an integral part of the radius rods in which case the lower rods might be joined to the upper at a point nearer to the front axle and be formed more. nearly in the form of a shorter projection or brace extending to the lower part of the front axle. I am aware that radius rods for supportin and holding the-front axle of} an automob' e in position have been constructed in the shape of two rods fastened to the front axle and extending backward under the crank case of the motor, joined together, and terniinateina round ball shaped extremitywhich is re ceived and heldin a Therefore, I do not claim and socket bearing nerally,"ibut I claim: i 1. g'lliecotnbinatmn with a V-shaped radius roclagforsmot'or' vehicles, the crotch of said rad an f swivel connection with socket bearing on the the transmission case of themotor vehicle and having its legs connected to the top of the front axle, of a sub-radius rod having an attachable and a detachable connection with the crotch of the radius rod and connected to the bottom of said front axle. 2. The combination with a V'shaped radius rod for motor vehicles, the crotch of said radius rod having a swivel. connection with the transmission case of-the motor vehicle and having its legs connected to the top of the front axle, of a .V-shaped sub-radius rod having an attachable and detachable connection with the .crotch of the radius rod and having its legs connected to the bottom of said front axle. I

3'. The combination with a V-shapedradiiis rod for motor vehicles, the crotch of said radius rod having a swivel connection With the casing of a power motive element of the motor vehicle and having its legs connected to the top of the front axle, of a sub-radius rod havinga connection atone end to said radius rod near its crotch and at the other end to said axle.

4. The combination with a V-shaped radius rod for motor vehicles, the crotch of said radius rod having a swivel connection with a fixed part of the motor vehicle and having its legs connected to the top of the front axle, of a V-shaped sub-radius rod connected at one end to said radius rod near its crotch and at its other end to said axle.

Signed at Clinton, in the county of Clinton, and State of Iowa, this first day of April, A. D. 1913.
